Thanks for the respsonse, in regards to your questions. The magenta and dark green links in the Weekly are just the Maximum 5Min data points that MRTG plots. Since the weekly graph is a condense day graph, it plots the high points, as well as average out the days to produce a readible graph.
The main data points I look at are the solid green, which is mu-mimo utilization, and the blue line, which is su-mimo utilization. To read the graph, the most recent data is on the left hand side and the older data goes to the right. So for the daily graph if you look at the right end of it you see that the SU-MIMO utitilzation was hovering around 60%, then when more data was requested and the sector kicked in MU-MIMO you would see the SU-MIMO decline and the MU-MIMO raise as I would expect.
After the update, it seems that the sector doesn't need to reach as high of a SU-MIMO utilization before MU-MIMO kicks in. The current graphs I have now show the MU-MIMO only reaching up to 85% but the throughput on the AP has not changed very much. I had originally limited our capacity to 70mbps in our QOS system so that customers speeds are shaped correctly and we could control congestion better and we would nearly reach that limit at nights. After the update I raised the capacity limit to 110mbps, but the highest level I have seen the AP reach is 90mbps.
From reading the explanation it seems that though MU-MIMO may be at 70% or 80% that doesn't necessarily mean I am at the peak capacity of the AP. Currently my AP shows that it is grouping about 3-4 at a time and occassionally at 5 when enough customers are online. My initial fear was that I was reaching the capacity limit of the AP because I had never seen the MU-MIMO utilization reach so high before and more constantly now.
